3 Claims.

This invention relates to smoking pipes, and its general object is toprovide a pipe in which the smoke passages thereof can be retained open,as all matter accumulating therein and tending to clog the same can beeasily and expeditiously removed therefrom, without necessitating theremoval or separation of the parts of the pipe from each other.

A further object of the invention is to provide a pipe of the straighttype, that is self-supporting in an upright position, and is constructedto prevent saliva or liquid from returning to the mouth of the user.

Another object of the invention is to provide i5 a pipe of the characterset forth, that is simple in construction, inexpensive to manufactureand extremely eicient in use and service.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claims, g

In describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is a top plan view ofthe pipe which forms the subject matter ofthe present invention.

Figure 2 is a sectional view taken approximately on line 2-2 of Figurel, looking in the direction of the arrows.

Figure 3 is a detail view illustrating the draft tube and the. scrapingor cleaning means that is housed therein.

Referring to the drawing in detail, the reference numeral l indicatesthe bowl of my pipe which as shown is of cylindrical conguration andincludes a flat bottom 2, with the result it will be seen that the pipeis self-supporting in an upright position, as indicated in Figure 2. Thebowl is provided with a vertical recess 3 disposed at the rear thereofand which communicates with the bore of the bowl, in the form as shown.Formed on and extending rearwardly from the bowl at the upper endthereof is an extension a that has tapered side walls merging into thebowl, as best shown in Figure 1. The extension 4 provides the stem forthe pipe and has a bore therein extending horizontally thereof forcommunica- I tion with the recess 3.

Mounted in the bore of the stem is a tube 5 of a length to extend to therecess 3 at one end and its opposite end portion projects beyond thestem to be received in a bore formed in one end of a mouth piece 5, thetube fitting the bore to frictionally secure the mouth piece to the stemand the mouth piece is further provided with a smoke passagecommunicating with the tube, as shown in Figure 2.

vIt will be noted that when the mouth piece is frictionally secured tothe tube 5 it is disposed iiush with the outer end of the stem foralignment therewith, and as the stem or extension d i is disposed abovethe bottom of the bore of the bowl, it will be impossible for saliva orliquid t0 return to the mouth of the user.

Removably mounted in the recess is what I term a draft tube 1 which isof a length to terminate above the bottom of the recess which has itslower end communicating with the bore of the bowl, and the upper end ofthe draft tube is closed as at 8 but has an opening therein for thepassage of the reduced upper end portion 9 lof a cleaning pin I0 mountedfor movement within the tube 1 and which is of a length to contact thebottom of the recess. The thick or major portion of the pin lll iscurved, to contact the wall of the tube l, for removing matter that mayaccumulate thereon, and it will be obvious that the matter is removed byrotating the pin, while the lower end of the pin is used to removematter that accumulates in the bottom of the recess, as well as inthelower portion of the tube l, thelatter being accomplished by moving thepin up and down. When the matter is removed from the wall of the tube 'land the recess 3, it can be easily blown into the bowl, as well as fromthe latter. 'I'he upper end of the tube 1 is disposed iiush with the topof the bowland the upperl end of the pin is bent upon itself to providea handle Il. The tube 1 is preferably held within the recess through theinstrumentality of a pin I2 that is disposed transversely of the bowland contacts the tube l, as clearly shown in Figure 2.

vArranged in the tube adjacent the upper end thereof is a slot I3 thatregisters with the inner end of the tube 5, so that a complete smokepassage is provided between the bottom of the bowl and the outer end ofthe mouth piece. The tube l not only acts as a housing for the cleaningpin l0, but likewise provides a draft means, to enable a better drawingaction in the event the bowl of the pipe is packed tight with tobacco,with the result it will be seen that my pipe has many advantages overpipes now in general use, and one of the important advantages is thefact that the mouth piece does not have to be removed from the stem, toscrape and remove matter that. f

Cil

accumulates in the smoke passage adjacent to and at its point ofcommunication with the bowl.

It is thought from the foregoing ldescription that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changesv fall within the scope of the appended claims.

What I claim is: l. A pipe comprising a bowl, a tube mounted in the bowland spaced from the lower end thereof for communication with the bore ofthe bowl, a stem extending at an angle from the upper end of `the bowland having a passage communicating with the tube adjacent the upper endof the latter, a mouth piece secured to the stem and means within thetube and mounted for movement therein to remove matter accumulating onthe walls thereof.

2. A pipe comprising a bowl having a recess arranged in the rear of thebore thereof. a tube having a closed upper end and an open lower end,the latter being spaced from the bottom of the recess and communicatingwith the bore of the bowl, a stem extending from the upper end of thebowl, a tube in said stem and having one end amarre and a handle for themeans and formed. on thel extending portion thereof.

3. A. pipe comprising a bowl, a vertically arranged tube secured in thebore of the bowl at the rear portion thereof and having an open lowerend communicating with the bore, a stem formed on the bowl at the upperend thereof, a tube extending through the stem and having one endcommunicating with the tube rst mentioned adjacent the upper endthereof, a mouth piece frictionally mounted on the second tube to besecured to the stem, a cleaning pin mounted for movement in the lrsttube and extending above the upper end thereof, said extending portionof the pin being bent upon itself to provide a handle, said pin beingcurved to contact the walls of the rst tube to remove matter therefrom,and the lower end of the pin being engageable with the bottom of thebore.
